Taurus Lifetime Repair Policy
I'm not positive if the Taurus Model 63 is covered by their Lifetime Repair Policy or not, but it very well could be.
According to the policy:
"...The Taurus Unlimited Lifetime Repair Policy™ is a commitment to repair selected Taurus firearm models FREE OF CHARGE for the lifetime of the firearm.....
...The Taurus Unlimited Lifetime Repair Policy extends to all Taurus USA firearm models in production prior to January 1, 2017...." --->>> https://www.taurususa.com/repair-policy.cfm
If there's any question, contact Taurus to see if it qualifies for the free lifetime repairs or not.
